FOLDING BOX.

Specification of Letters Patent.

Patented Apr. 3, 11917.

Application filed August 24, 1916. Serial No. 116,718.

To all whom it may concern:

Be it known that I, CHRISTIAN S. LEH- MAN, a citizen of the United States, residing at Lawn, in the county of Lebanon and State of Pennsylvania, have invented certain useful Improvements in Folding Boxes, of which the following is a specification, reference being had therein to the accompanying drawing.

The ob 'ect of my invention is to provide a knockdown box, preferably formed of cardboard, consisting of a creased blank provided with metallic fasteners holding the parts in their proper relation when 1n knockdown position, and also securing the various parts when folded to form a box.

My improvement may be employed in a box cover as well as in the box proper and it is therefore my intention to be understood as including within my invention the application thereof to each or either of said parts of a box.

Reference is to be had to the accompanying drawings in which like reference characters indicate like parts throughout the several views.

Figure l is a plan view of the blank, showing the creases in same.

Fig. 2 is a plan view of the box in its knock down position.

Fig. 3 is a perspective view of one corner v of the box, looking from the inside, with the end turned up.

Fig. 4 is a similar view looking from the outside. 7

Fig. 5 is a perspective of one corner looking from the inside with the upper part of the end turned over to secure the varlous parts.

In the drawings, a rectangular blank is shown, the body 1 of which is adapted to be folded upon the lines 2 parallel with each side of the said blank to form sides 3 for the said box.

The blank is also adapted to be folded upon the lines 4 parallel with the sides of the blank, and intersecting the lines 2 at 5, to form the ends 6 of the box. The corners of the said blank are also adapted to be folded upon a diagonal line 7 extending from the points 5 t0 the respective corners of the blank, to form an inturned fold 8 which rests against an adjacent inturned fold 9- secured to the end of the box when properly assembled. A retaining flap 10 is folded upon the line 11 extends outwardly from each of the end members 6 between the lines 2.

When in its knock down position, the blank is folded as shown in Fig. 2, with the side 3 bent down uponthe blank proper and having the fold 9 secured to the underlying end member 6 by the inner end of longitudinally extending metallic wire 12 hooked through said end and fold. The outer end of the wire 12 is similarly hooked through the flap 10, the body of said wire thereby crossing the line '11, upon which the flap 1O folds, at right angles.

\Vhen it is desired to form a box from a knock down blank as just described, the sides 3 and ends 6 are bent" upwardly as shown in Figs. 3 and 4 the folds 8 resting against the folds 9. The retaining flaps 10 are then bent over and down to lie against the respective ends of the box above the folds 8 as shown in Fig. 5, the wires '12 being also bent upon this line 11, holding the retaining flaps in position without the necessity of additional fastening means.

Thus it will be seen that I have provided a knockdown box of simple construction, which may be readily formed into a box without the use of separate fasteners of any kind.

I'claim as new in my invention:

A folding box formed from a blank including a body, foldable end walls extending therefrom, side walls foldable so that their outer portions overlie the outer portions of the end walls, the outer portions of the side walls being foldable on diagonal creases when the end walls are folded, retaining flaps extending from the outer edges of the end walls and foldable to embrace the folded outer portions of the side walls, and bendable fasteners each having one end anchored in the blank to hold the extreme outer portions of the side and end walls to each other and having the opposite end anchored in the retaining flap so as to be bendable with the retaining flap for clamping the folded outer portions of the side walls between the flaps and end walls.

In testimony whereof I affix my signature.

CHRISTIAN s. LEHMAN.
